DETERMINATION OF THE FLUIDIZATION REGIMES OF BICOMPONENT BEDS OF SOLID PARTICLES AND THE CHARACTERISTIC VELOCITIES OF A GAS IN THESE BEDS BY THE PULSATIONS OF THE DIFFERENTIAL PRESSURE IN THEM

摘要

The possibility of determining the regime of fluidization of a bicomponent bed by the dependences of the statistical characteristics of the pulsations of the different pressure in this bed on the velocity of the gas blown through it is demonstrated. An algorithm of estimating the characteristic gas velocities corresponding to the transformation of the bed into the regimes of fluidization and turbulent fluidization at room temperature and at much higher temperatures has been developed. This algorithm allows one to determine the indicated velocities more exactly, as compared to the traditional methods, by the dependence of the differential pressure in the bed on the velocity of the gas blown through it.
